My counselor has relapsed

Expecting My 🌈
I've been seeking a counselor since my 3rd child died, my aunt died and my dad died this all happened with in 4 month Span,well my counselor is supposed to see me 3 times a week she comes maybe twice a month, she told me she used drugs in the past but got over her addiction and graduated from college and went on to get clean and now she is a counselor... Well she has relapsed on drugs and alcohol and everytime I see her she is high off something or drunk ....she comes to my house and smoke weed with my neighbors and shouts to everyone she is my counselor which I wanted that to be private that I have a counselor, she also stole my xanax yesterday when I told her go get them from the pharmacy she pocketed three out of my bottle and told me later that day, she came picked me up from work and she told me she was drunk and high and she almost killed us I told her to let me drive her home and I'll just find me another ride home... She begs me to not tell her and to don't leave the company because they pay her 500$ to counsel me... At this point I just don't know what to do because I feel like she is very toxic to me and I'm already going through alot and she just makes it worse... She apologizes so many times for her fuck ups and I'm so tired of her... She promised me she would bring me to my sister wedding and an hour before she stood me up and told me she fell asleep and told me she had to test me to see how strong I was, so I missed my big sister wedding I cried all weekend and she goes to say you didn't even need to go to that wedding... I understand she going through alot and she needs money but this is just not right, what can i do?
